摘要： In order to allow the surgical operator and his assistant to make stereoscopic viewing of the region of surgery with a same magnification and in coaxial relationship, the surgical microscope comprises: a common objective lens; a pair of variable magnification optical systems disposed on the image side of the objective lens; and a pair of light beam splitting members disposed on the image side of the pair of variable magnification optical systems, respectively, wherein arrangement is provided so that paired observational optical paths are to be directed to extend respectively in a plurality of directions each having a predetermined angle relative to a plane containing the optical axes of the pair of variable magnification optical systems, within a plane crossing these optical axes at right angles, respectively. The pair of light beam splitting members are constituted as an optical path splitting unit, and the barrel section and the optical path splitting unit are removably coupled to each other.

摘要： In order to allow the assistant also to make an observation of the same region of the object as by the surgical operator in the form of a normal and clear stereoscopic image, and to enable the size of the barrel as well as the price to be about the same as that of an ordinary surgical microscope having two optical axes, the surgical microscope of the invention is arranged so that by the employment of two pairs of prisms each having a polarized light beam splitter section and a total reflection surface, a pair of operator's observational optical systems and a pair of assistant's observational optical systems are used partly in common, and one of the polarized beams so split by the polarized beam splitter section is utilized as the operator's observational light, and the other is utilized as the assistant's observational light. One pair among the two pairs of prisms is constructed as a first stereoscopic view adapter, and the other pair as a second stereoscopic view adapter, and the common portion of the observational optical systems mentioned above is constructed in the form of a barrel, and all of these constituent parts are removably coupled to each other.

摘要： An adaptor for microscopes provided with a first reflecting device reflecting incident light an even number of times to emit the light in a direction making a predetermined angle with the incident light and a second reflecting device capable of rotating around a shaft positioned near a center of gravity so as to be made to rest on two predetermined positions and reflecting once the incident light coming from the first reflecting device to emit the light in either direction of the mount for the TV camera or the mount for the still camera, in order to minimize vibration generated in rapid switchover between the TV camera mode and the still camera mode, bring about an image exhibiting the right side in any use of the TV camera and the still camera, and make it possible to be designed for a small size. The first reflecting device comprises a prism having a pair of opposite reflecting surfaces or a pair of mirrors in which reflecting surfaces are opposite to each other, while said second reflecting device includes a single mirror or a double mirror.
